AFAIK there’s no native way to do that.
“Export tracks” or making a template are the only Cubase options. Neither one is optimal.
Alternatively you could buy Vienna Ensemble Pro and create the same track configuration in VEP and save the track configuration as Cubase track preset. Thats the way I do it sometimes. Whats even easier is to use something like Native Instruments Kore and save it as a Kore preset. Maschine can do that too but the interface is too “beat oriented” for my liking.
